Do Plants Like Starch Water?

Starch water, also known as starchy water, is the water that has been used to boil or cook vegetables, potatoes or rice. It becomes slightly thick and cloudy due to the release of starch from these foods. While humans may discard this water, some gardeners may be inclined to use it to water their plants. But the question is, do plants like starch water?

The Benefits of Starch Water

Starch water contains a small amount of nutrients, such as starch, vitamins, and minerals, that can be beneficial for plants. When used in moderation, it can provide a gentle source of fertilizer to promote plant growth. Starch water may also increase the water retention of soil, helping to maintain soil moisture levels for plants.

Watch Out for Excess Starch

While starch water may have some benefits for plants, it can also have negative effects if used in excess. Excess starch can change the pH level of soil, making it too acidic, which can be harmful to plants. Additionally, starch water can attract pests, such as ants, flies, and rodents, which can damage or destroy plants.

Consider the Type of Plant

The effect of starch water on plants can depend on the type of plant. Some plants, like corn and bananas, naturally contain a lot of starch, so watering them with starch water may not have much impact. On the other hand, plants that prefer slightly acidic soil, such as azaleas, rhododendrons, and blueberries, may benefit from a small amount of starch water, as it can help to lower the pH level of soil.

Conclusion

In conclusion, the answer to whether plants like starch water is not straightforward. While it can have some benefits for plants, such as providing a gentle source of fertilizer and increasing soil moisture retention, it can also have negative effects if used in excess, such as changing the pH level of soil and attracting pests. When using starch water on plants, it's best to use it in moderation and consider the type of plant being watered. As with any substance, it's always best to err on the side of caution and do some research before using it on your plants.
